9.获取错误信息并到指定页面
1 protected void Application_Error(Object sender, EventArgs e)
2 {
3 if (Server.GetLastError() is HttpUnhandledException)
4 Server.Transfer("MyErrorPage.aspx");
5 }
6
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理2 {
3 if (Server.GetLastError() is HttpUnhandledException)
4 Server.Transfer("MyErrorPage.aspx");
5 }

10.清空Cookie
